Definitions
- the invention relates to a method according to the preamble of claim 1.
- Such a method is known from DE-A1 2 831 297.
- the arithmetic unit there processes only two-stage binary information.
- the invention has for its object to provide a method for detecting edge structures in an image signal, which is particularly suitable for edges with an orientation that are not horizontal, vertical or at 45 ° to the horizontal, with less effort than it was previously possible to recognize; the method should be suitable for processing still images.
